The looker blog post addresses this though the google one doesn’t:
> For customers and partners, it’s important to know that today’s announcement solidifies ours as well as Google Cloud’s commitment to multi-cloud. Looker customers can expect continuing support of all cloud databases like Amazon Redshift, Azure SQL, Snowflake, Oracle, Microsoft SQL Server, Teradata and more.
Time will tell - but I suspect we’ll see new features will be “bigquery first”
Look to Stackdriver for guidance: it originally supported AWS and they haven’t removed it in the years since acquisition. I think it’s safe to assume Looker will support many non-GCP datasources for a very long time.
